            const filter = (reaction, user) => {

              if (reaction.emoji.name === "📪"){
                
              
                reaction.users.remove(user);
                reaction.message.channel.delete();
              }


            return reaction.emoji.name === '📪' && user.id === message.author.id;  
          }
          const collector = message.createReactionCollector(filter, { time: 15000 });

          collector.on('collect', (reaction, user) => {
            console.log(`Collected ${reaction.emoji.name} from ${user.tag}`);
          });

          collector.on('end', collected => {
            console.log(`Collected ${collected.size} items`);
          });
              


          });
  
        
        }
      }
    }
)

You need to use the right filter. As I can see, you want to only detect reaction from the message author. So put these restrictions into the filter and then every reaction collected by the collector will respect these conditions.

Now that you have this, just execute whatever you want and stop the collector once everything is done so you will not listen to any other reactions.

let sent = await channel.send(`<@${user.id}>`, new Discord.MessageEmbed()
  .setTitle("Welcome to your ticket!")
  .setDescription("We will be with you shortly")
  .setColor("00ff00")
);
sent.react('📪');

const filter = (reaction, user) => {
  //We filter the collector to only listen to 📪 reaction added by the author of the message.
  return reaction.emoji.name === '📪' && user.id === message.author.id;  
}
const collector = message.createReactionCollector(filter, { time: 15000 });

collector.on('collect', (reaction, user) => {
  console.log(`Collected ${reaction.emoji.name} from ${user.tag}`);
  reaction.users.remove(user);
  reaction.message.channel.delete();
  //Then we stop the collector.
  collector.stop()
});
